RX 470 4GB + FX-8320 + Windows 10 x64 - GPU usage low \ FPS low

Question asked by flargargoyl on Feb 27, 2017

Describe your system:

  • XFX RX 470 4 GB
  • Desktop, ASUS SABERTOOTH R2 motherboard, 2x8 GB ram 1600 MHz (dual channel)
  • Windows 10 x64 PRO, all updates installed. Drivers 16.9.2

    • Display Devices
      • 3X Dell U2311H, connected via DP 1.2
    • Motherboard
    • CPU/APU
      • FX-8320
    • Power Supply Unit  Make, Model & Wattage
      • CoolerMaster 1200 W
    • RAM
      • 2x8 Gskill 1600 mhz

    Issues i`ve met:

    1. Radeon Software Crimson finds new driver, 17.x.x (several of them already was in that list). If i update it via interfeace of Crimson firstly, at some point of installation process, my image on monitor goes crazy - wrong colors, wrong resolution or black screen`s all over. Tried about 6 times.

    If i use DDU | AMD removal software (in Safe Mode as described), and install same 17.xx version of drivers from off.site - same issues with image.
    I`ve waited for about 40 minutes to let the install process finish. I can`t say 100% it finished as my image corrupted, but after that i peform a shutdown (with a power button but not force - single-press calls shitdown event) and turn on my PC, image looks OK BUT i have no Crimson software and can`t seems to install it "separately". Also, as my image was corrupted during isntallation process i`m quite not sure it`s OK to use this drivers, 17.2.xx \ 17.1.xx.
    What should i do with bug`s with 17.xx drivers in general? Again, i`ve tryed the DDU \ AMD removal tool in Safe Mode several times, with reboot on each corresponding step.

     

    2. Strangely, low GPU usage AND game performance with drivers 16.xx, examples:
    Witcher 3, Ultra (excluding some Ngreedia-related hairworks stuff, and PhysX library removed from a game folder) - all perfect. Mostly 60 FPS, GPU usage is mostly near the 100%, CPU usage above 70%, OK performance.
    Even with Eyefinity with 3x 1920*1080 monitors on High preferences, performance is OK. Which wonders me as it`s an Ngreedia title, etc.
    Bad performance with:

     

    Far Cry 3
    Far Cry 4
    Far Cry Primal
    All of 3 above - same symptoms. Either with DirectX 9 or 10\11+, does not resolution-dependant, different settings of graphics - not related. FPS is jumps all over between 1 and 60 (if Vsync is ON or 120+ if no Vsinc), GPU usage mostly jumps between 10 and 40%. CPU is not above 60% in all cases.
    I`ve spent like 30 hours experimenting with game settings. Even with ultra-low for everything AND modifications to game graphics preferences file to access some engine`s stuff that not accessible via game UI, i STILL have an average FPS around 20-25 and low GPU usage. Most stunning stuff is if i have a dynamic action, a lot of explosions, moving objects etc - GPU usage rises and i have 60 FPS. But the jumps between is bugging me off.

     

    Saints Row the Third is a bit different. Most symptoms are the same, except - with DirectX 9 FPS is under 20 all the times, does not matter if preferences are ULTRA or OFF\LOW.
    With DirectX 10\11 - HUGE performance changes, like, 160+ FPS in the building, and 20-40 FPS at street. Barely depends of preferences, GPU and CPU usage is again, pretty low.

     

    I`ve used Crimson to up the Power LImit to 10 and then 20% (in GLOBAL section) - looks like it helped with Saints Row but not with any of Far Cry`s

    Energy efficiency does nothing as i can see for this case.
    To test the source of this problems i even dropped of my O.C. on CPU\RAM, running STOCK values on everything.
    WIndows Power Efficiency - tested all economic, High performance and balanced. 
    PSU is OK 100%, two weeks ago it served TWO GTX 660 TI PE WITH O.C. in SLI mode without any problems. I`ve changed cable between PSU and Graphic Card as i had a possibility (module build PSU) and the port on the PSU so it`s not power supply issue on this end.
    This is not CPU bottleneck issue either as i have a pretty amazing performance on several game that no one will ever call "resource merciful".

    Problem is not related to the Physical Resources as well, because iv`e checked, configured and changed several times the I.R.Q. tables, Input\Output bus, used another PCI-E port, etc.
    Obviously there is no overheat in any thing, GPU on Witcher is around 68 C.
    I am 95% sure that this issue is related with:
    Drivers
    OS tuning (?)

    My wrong-assigned-hands although i`m an IT guy with some experience.


    I did not checked yet: use another Win 10; use another Win version; Moon phase; Greek Gods will;
    As you might probably see, i`m kind of desperate here in search of get my performance out of this hardware, especially that usually i do understand how it works and why not, but not this time.
    What should i check? Any registry stuff? Some special driver version?
